Abstract
Abstract A portable partition wall system which is lightweight, easy to maintain, requires no finishing trim, and can be assembled and disassembled without any tools. Wall panels consisting of a velcro loop fabric bonded to a polyester foam core are joined together by Velcro hook tape. The panel core has a central groove along its edges into which the Velcro loop fabric is inserted and glued to prevent premature separation of the fabric and core.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
145 words
A knock-down wall system for joining a panel to a static member, comprising: a panel comprising: a core comprising a pair of major surfaces connected by an edge surface, said edge surface defining a groove therein; an adhesive binding agent applied to said major surfaces and to said groove; and loop fabric applied to both said major surfaces and extending from both said major surfaces into said groove, said fabric being adhered to said major surfaces and to said groove by said adhesive binding agent; and hook fastener tape extending substantially the same length as the length of said groove, said tape being attached to said static member; said grooved edge surface of said panel being removably joined to said static member solely along said hook fastener tape by interconnection of said hook fastener tape with said loop fabric on both sides of said groove.
Claim 2
Dependent Claim
145 words
A knock-down wall system for joining a panel to a static member, comprising: a panel comprising: a core comprising a pair of major surfaces connected by an edge surface, said edge surface defining a groove therein; an adhesive binding agent applied to said major surfaces and to said groove; and loop fabric applied to both said major surfaces and extending from both said major surfaces into said groove, said fabric being adhered to said major surfaces and to said groove by said adhesive binding agent; and hook fastener tape extending substantially the same length as the length of said groove, said tape being attached to said static member; said grooved edge surface of said panel being removably joined to said static member solely along said hook fastener tape by interconnection of said hook fastener tape with said loop fabric on both sides of said groove.
Claim 3
Dependent Claim
22 words
The system of claim 1, wherein said panel comprises a synthetic resinous foam board, said groove being defined in said foam board.
Claim 4
Dependent Claim
11 words
The system of claim 2, wherein said foam board comprises polystyrene.
Claim 5
Dependent Claim
21 words
The system of claim 1, wherein said groove has a width such that said fabric and adhesive substantially fill said groove.
Claim 6
Dependent Claim
28 words
The system of claim 1, wherein said hook fastener tape is double-sided and wherein said static includes loop fabric attached to one side of said hook fastener tape.
Claim 7
Dependent Claim
13 words
The systems of claim 1, wherein said fabric includes a breathable jersey backing.
Claim 8
Independent Claim
148 words
A method of joining a panel to a static member to make a knock-down wall system, comprising the steps of: forming a core so as to define a pair of major surfaces connected by an edge surface, and a groove in said edge surface; applying an adhesive binding agent to said major surfaces and to said groove; applying a loop fabric to both said major surfaces and extending said loop fabric from both said major surfaces into said groove, said fabric being adhered to said major surfaces and to said groove by said adhesive binding agent; attaching hook fastener tape extending substantially the same length as the length of said groove to said static member; and joining said grooved edge surface to said static member solely along said hook fastener tape by interconnection of said hook fastener tape with said loop fabric on both sides of said groove.
